An overview of studies in 2013 found that high GI foods – which include fizzy drinks, pastries, cakes and chocolate – have a direct impact on the severity of acne.

This is because they absorb into the bloodstream quickly causing a fluctuation of hormones, including insulin, thought to instigate oily secretions (called sebum) that leads to spots.

2) …and younger

Eating a lot of sugar can have an ageing effect, it turns out.

A study by Leiden University found that those aged between 50 and 70 who had a high level of glucose in their blood consistently looked older than people whose blood sugar level was lower. For every 180 grams of glucose per litre in participants’ blood, their age guessed by others rose by five years.

‘Normally collagen bulks out the skin and gives it a younger plump look,’ Dr Ross Perry, a cosmetic doctor at the Cosmedics clinic in London explained to the Mail Online.

‘If you persistently eat a high-sugar diet, then as a result, the collagen and elastin will become more rigid, so it will become easier for wrinkles to form and the skin will lose that youthful plumpness.’

3) You’ll sleep better

Diet, sleep and energy are all things that are interlinked. Once sugar is cut out of your diet, it’s no wonder that you’ll notice a change to your sleep pattern.

This 2016 study that examined the impact of different food groups on sleep found sugar to be one of the ones impacting our quality of slumber.

Saturated fat and sugar were found to lessen time spent in deep sleep mode.

4) Your heart will be happier

Looking at the impact of sugar on the risk of cardiometabolic diseases, he found that sugar may as related to high blood pressure and hypertension, as sodium. The research suggests the link could even be greater.

Those who consume 25% or more calories from added sugars have an almost threefold increased risk of cardiovascular disease than those who don’t.

5) You might be in a better mood

That self-loathing after you eat a doughnut may have more of a scientific basis than you would have thought.

Studies into the impact of sugar-rich foods on the moods of post-menopausal women found that it was a risk factor in the development of depression.

It is caused by the sugar being easily absorbed into the blood that can make you feel irritable and moody later on.

Meanwhile the higher consumption of lactose, fibre, nonjuice fruit, and vegetables was associated with lower odds of depression in the study.

6) You’ll remember the name of your partner’s boss

Or your friend’s boyfriend or whatever else you’re likely to forget on a fairly regular basis.

The good news for people who can be a bit forgetful sometimes is that ditching sugar is good for your brain.

This UCLA study found a link between a diet heavy in sugar and impaired brain function. It was found that the increased administration of fructose had a particular impact on the memory of animals tested.

So cutting out the sugar might mean you’ll be feeling a bit sharper in the office.
